<p>TITLE FABRICATION METHOD FOR MIXED OXIDE FUEL Inventor Melville A. Feraday A mixed oxide fuel fabrication method using a starting material of an oxide of a first fuel in the form of spherical particles of two size fractions, fine and coarse, the process comprising sintering the fine fraction to full density sintering the coarse fraction to a predetermined density such that the porosity will allow enrichment, impregnating the coarse fraction with a salt of a second fuel material and treating this fraction to convert the impregnating material to an oxide and then loading both fractions into a fuel element sheath and compacting. In the preferred process three size fractions are used i.e. fine, medium, and coarse with only the coarse-fraction being subject to the impregnation step.</p> |
